This is a stupid one, but have you taken the gun apart? I've noticed that when I have some of my mags sitting for a long while, The bolt sticks to the rubber bumper enough that it won't shoot. All I have to do is remove the valve and pull off the bolt from the valve and put it all back together.

try a shorter spring and or turn up the velocity more. I had to crank mine to the point where it would vent originally and it would still not shoot. I had to replace the reg piston ( x valve) to get it to work properly.

level 7 spacers and level 10 carriers are completely different animals. do not interchange them.

the bolt should slide off if you hold the valve body up, not the other way around.

Backing up a bit, what exactly did you buy and what are you putting it in? Did you buy just the bolt or the whole kit? What did you do to put it in, just swapped bolts?

I bought a valve with Level 10 bolt. I'm sure it's a level 10 bolt and it looks like the level 10 spacer also. The person I bought it from said it was untested, they were just reselling it... I should've known to pass on it

All it has is the short (or medium?) spring and i dont have any extra parts
